This article describes ZEW-EviSTA®, the microsimulation model developed and used at ZEW - Centre for European Economic Research in Mannheim. The model simulates the German tax and transfer system using household micro level data. By estimating fiscal effects, labor market outcomes as well as...

This paper proposes a method for integrating individual effective tax rates and marginal tax rates computed from a microsimulation (partial equilibrium) model of tax policy with a dynamic general equilibrium (DGE) model of tax policy that can provide macroeconomic analysis or dynamic scores of...

This paper develops and calibrates a simple general equilibrium model with two types of labor and capital for the French economy. The simulation results indicate that targeted reduction in employer social security taxes, financed by a broad-based income tax, have six times as large an effect on...

We explore the efficacy of price and quantity controls in a dynamic set up in which the decisions of some agents are irreversible. We demonstrate that the assumption of irreversibility improves the performance of a tax relative that of a system of tradable quotas and significantly alters the...

Gasoline taxes vary widely among industrialized countries, as does support for the United Nations' effort to curtail the use of fossil fuels to address the climate change problem. We argue that malapportionment of the electoral system affects both the rate at which governments tax gasoline and...

Natural-resource taxation and investment exhibit cycles in a vast number of countries, driving political turmoil and power shifts. Using a rational-expectations model, we show cycles result from governments' inability to commit to future taxes and firms' inability to credibly exit a country...

This paper assesses the current Colombian mining tax and royalty regime in terms of efficiency, competitiveness and revenue performance vis-a-vis other relevant mining countries. It then discusses the convenience of introducing a Resource Rent Tax (RRT) to new mining projects (together with a...

Zambia has changed its mineral tax regime repeatedly during the past decades in a bid to raise mineral revenue, but with only modest success. This paper looks at what the country needs to do to create a mining fiscal regime that could sustain operations, boost output, and raise revenues without...

This paper examines pollution and foreign-capital tax policies on the host country?s welfare when foreign-investment tax credits are absent or present in the source country. In the absence of tax credits, the optimal policy is a pollution tax with a foreign-investment tax or subsidy. The...
